Test/Review index of all tested usb chargers, any comments?

If you make the skulls slightly smaller you can fit three on the line if you wanted. For example:

1 - Failed 5000v test

2 - Failed 2500v test

3 - Failed in some other way also

OR you can create a skull icon that is half filled with red and use that for a half skull maybe.

The skulls are good though.

Regarding CE testing - Is it true that if a product passes European CE testing then it is automatically passing UL/US testing because the European testing is more stringent?

Thank you.

Short answer: no

Lots of contries uses the 60950-1 standard for electric safety in IT equipment. It is useable all over the world because safety is graded depending on voltage, i.e. 120VAC does not require as much safety distance as 230VAC, but it does also have some chapters for specific countries.

Before a product is legal is must fulfill many more standards, in CE countries it can be EMC (Does it disturb radio equipment is is disturbed by radio equipment), energy consumption, mechanical safety. Usual a CE "approved" product is delivered with a page saying what standards it fulfills.

Inside CE country you do not need a certificate saying that you are fulfilling these standard, you can just write your own, but any government safety department can ask you (if you are importer or producer) for a technical file that proves the testing and the result and you must provide that within a few days or risk fines and product recall.

UL does their own testing and makes a certificate for you, it is possible to ask them to do both UL and CE tests at the same time and save some money (Something like 60950-1 only have to be tested once).

I have tried adding a small check mark, instead of the empty box. I hope this is better.

Thanks for your great work!
I’m curious about Leagoo 1A Charger I own one and it seems well made and does provide 1A current, but I have no way to test it’s safety and noise. If it’s good it might be a nice cheap option.

I have ordered one.

BG have a few “New arrivals” with the brand Ldnio. They are all descibed as “Safe and easy to use and carry”
Any plan to test any of these?

You can always open up any unknown charger and check it visually to start with. If there is no place on the circuit board where you see a separation of some of the circuit traces from the rest then its isolation may be bad, dangerous. If you do find a decent separation then you can move on to look for a capacitor bridging the two sides. There may not be one but if there is then it must be a safety capacitor (which will have more markings). You can post picture if unsure of anything.

The problem with opening the charger is that it often "destroys" it.

I plan on testing many usb chargers and I will be looking at the suggestions posted here.

They are expensive enough to be good, I am very curious about them.

I have ordered one and put the rest on my shopping list and will probably order them during the next week. Due to the price I have to order one at a time, if I get two in one package custom will give me a $22 fine.

Great! :slight_smile: They sure have some fancy compliance markings written on them. Hopefully they are legit. Looking forward to your tests!

It is easy enough to print the marks on the charger, it is much harder to live up to them. If the marks are legit there is some serious testing behind them.

Just be aware of the time frame, I will not publish any review soon. At the current time I have about 10 usb chargers in queue and I doubt I will publish much more than one each week (I may get time during Easter to publish a bit more, but them I also have other stuff).

I just want to tell you how much I appreciate your excellent reviews. I find them very useful. It’s nice to have factual information upon which to base purchasing decisions.

HKJ - Thank you for the clarification on CE & UL testings!

All of them are on the way.

Some usb chargers do get hot, I have just tested a multiport one that got above 100°C on the plastic.

Ouch, that is hot! Looking forward to the reviews, in a month or two.

God helg!

It is hot and probably means it will get a bad rating (I am still missing the 5000 volt test and the tear down).

A month or two before I publish the first one is probably correct, but the last one will take a bit more time. I do have about 10 in queue at the current time. It looks like I am going to test a lot of usb chargers in 2015.

I am still open for suggestion about other chargers to test. The most interesting is not chargers that is expected to fail (i.e. models below $3), but cheaper chargers that are good.

Thank you. In Denmark we usual says "God weekend", but it is only valid for Saturday/Sunday, not for something like Easter.

For me that often means time to write the reviews and do the manual part of testing stuff (The automatic part is running 24/7).

Conrad has some interesting high-power USB chargers. They are pretty big/popular in Europe, so some reviews of the chargers they sell might be interesting, since they are very easy to source in EU and pretty cheap.

For instance a 24W 2x2,4A charger:

Or a 25W 5X charger:

Can you test one of the Anker chargers? I've been quite pleased with the 5 port, 40 watt model

I have ordered all 3 chargers, depending on what sequence I publish in, it can be a couple of months before the review is published.
